Winform调用百度地图接口简单示例

 

1、首先用一个html文件调用百度地图接口(主要注册一个序列号):

 

 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">  <html xmlns="http://www.w3.org/1999/xhtml">  <head>      <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />      <title>百度地图的Hello World</title>      <style type="text/css">          body, html, #allmap          {              width: 100%;              height: 100%;              overflow: hidden;              margin: 0;          }          #l-map          {              height: 100%;              width: 78%;              float: left;              border-right: 2px solid #bcbcbc;          }          #r-result          {              height: 100%;              width: 20%;              float: left;          }      </style>      <script type="text/javascript" src="http://api.map.baidu.com/api?v=1.5&ak=6c497f51c06477544e5fa6e9bd68f7c3"></script>  </head>  <body>      <div id="allmap">      </div>  </body>  </html>  <script type="text/javascript">      //alert("Hello World");      var map = new BMap.Map("allmap");               // 创建Map实例      var point = new BMap.Point(121.504, 31.212);    // 创建点坐标(经度,纬度)      map.centerAndZoom(point, 11);                   // 初始化地图,设置中心点坐标和地图大小级别      map.addOverlay(new BMap.Marker(point));         // 给该坐标加一个红点标记      //var traffic = new BMap.TrafficLayer();         // 创建交通流量图层实例           //map.addTileLayer(traffic);                     // 将图层添加到地图上         map.addControl(new BMap.NavigationControl());   // 添加平移缩放控件      map.addControl(new BMap.ScaleControl());        // 添加比例尺控件      map.addControl(new BMap.OverviewMapControl());  //添加缩略地图控件      map.addControl(new BMap.MapTypeControl());      //添加地图类型控件      map.setCurrentCity("上海");                     //设置地图显示的城市      map.enableScrollWheelZoom();                    //启用滚轮放大缩小      function setLocation(x,y){//参数:经纬度           var point = new BMap.Point(x, y);              map.centerAndZoom(point, 11);                             map.addOverlay(new BMap.Marker(point));            }  </script>  

 

 

 

 



2、建立一个Winform项目,用一个WebBrower控件查看html文件、调用JavaScript代码

 
using System;  using System.IO;  using System.Collections.Generic;  using System.ComponentModel;  using System.Data;  using System.Drawing;  using System.Text;  using System.Windows.Forms;  namespace BaiDuMap  {      public partial class Form1 : Form      {          public Form1()          {              InitializeComponent();          }          private void Form1_Load(object sender, EventArgs e)          {              try              {                  //webBrowser1.Url = new Uri("http://www.2345.com");                  //这个文件于可执行文件放在同一目录                  webBrowser1.Url = new Uri(Path.Combine(Application.StartupPath, "GoogleMap.htm"));              }              catch (Exception ex)              {                  MessageBox.Show(ex.Message, "异常", MessageBoxButtons.OK, MessageBoxIcon.Error);              }          }          private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)          {              //这里传入x、y的值,调用JavaScript脚本              webBrowser1.Document.InvokeScript("setLocation", new object[] { 121.504, 39.212 });          }      }  }
